Objective: Oral squamous cell carcinoma involving the maxilla (MSCC) is a rare malignancy. The aim was to perform a systematic review and meta-analysis of available literature on local recurrence (LR), overall survival (OS), and associated risk factors of MSCC. Study Design: The Cochrane, PubMed, and EMBASE databases were searched with related keywords and synonyms. The pooled proportions of both LR and OS were subsequently calculated with 95% confidence intervals. Results: In total, 2638 articles were screened on title and abstract, 131 articles were screened on full text, and 20 were included. The pooled 5-year LR rate was 19.3%, and the 5-year OS rate was 53.7%. The subgroup analysis between surgery only and surgery with (neo)adjuvant treatment resulted in an odds ratio (OR) of .76 (95% confidence interval [CI]; .41-1.40). Conclusions: Postoperative (chemo)radiotherapy or preoperative intra-arterial chemoradiotherapy improves survival when adverse tumor characteristics are present. Posterior tumor extension into the soft palate, pterygoid muscle, pterygoid process, and infratemporal fossa was significantly associated with decreased OS in multiple studies. More research into the risk-reduction of local recurrence is warranted.
